Frequently Asked Questions (FAQ) Pipette Pump 25ml

Q1: Does the pipette pump 25ml work with all types of pipettes?

Yes. The pipette pump 25ml fits all standard glass and plastic serological pipettes with the common tapered tip design. It works with 1ml, 2ml, 5ml, 10ml, and 25ml pipettes using the same universal nozzle.

Q2: Can users use the pipette pump with corrosive chemicals?

The ABS plastic body and silicone valves resist mild acids, bases, and most common organic solvents. However, users should avoid prolonged contact with highly concentrated strong acids like concentrated sulfuric acid or fuming nitric acid, as these can degrade the material over time.

Q3: How do users clean the pipette pump 25ml?

Users disassemble the lower section by unscrewing the nozzle cap, remove the cotton filter, and rinse the internal bellow with distilled water or 70% ethanol. They allow all parts to air dry completely before reassembly to prevent contamination during future use.

Q4: How often should the cotton filter be replaced?

Users should replace the cotton filter whenever it shows visible discoloration, moisture, or signs of contamination. Under normal conditions with dry reagents, the filter lasts several months. Laboratories that frequently handle volatile or corrosive liquids should replace it monthly.

Q5: Is the pipette pump 25ml autoclavable?

The silicone valves and cotton filter tolerate autoclaving at 121°C. However, the ABS plastic body typically does not withstand repeated autoclave cycles. Most laboratories use chemical disinfection with 70% ethanol or 1% sodium hypochlorite solution for the body.

Q6: What is the difference between the 25ml pipette pump and the 10ml version?

The 25ml version has a larger bellow capacity and fits larger serological pipettes. It typically comes in red to distinguish it from the blue 10ml and green 2ml versions. The internal mechanism is the same, but the larger bellow delivers more suction volume per wheel rotation.
